About a month ago I had a cyst injected with kenalog twice. A week later an indentation developed. Is it permanent?

Our office specializes in scar revision. Atrophic or indented scars can be improved with fat transfer harvested from another part of the body. The fat can be purified and transferred into the indentation. You may consider removing the cyst prior to scar correction. Raffy Karamanoukian MD FACS

Thank you for your
question. A picture would be helpful.In general, it takes a full year for scars to mature and for you to know your final results. I have attached scar care instructions that you may find helpful.

To be sure, see
two or more board-certified plastic surgeons in your area for a full and
complete evaluation.

I hope this helps.

Kenalog injections can cause a temporary indentation or atrophy.  Depending on the amount used and the location of the injection, the atrophy may last for a few to many months.  Treatment is not usually necessary, but if the depression is very obvious, hyaluronic acid fillers can be used to temporarily fill in the area.  You do not want to use a long-lasting or permanent filler since you will have over-correction as your own skin recovers. Laser treatment will not help. 

It sounds like you have developed atrophy of the injected area. In some cases, this will resolve without any need for further treatment. In other cases, this can require fillers or other treatments to remedy the "scalloped" area of tissue. Your best bet at this point is to followup with the doctor that performed your steroid injection and inquire about your options. At this point, time is on your side and I wouldn't recommend any aggressive treatments. Stephen Weber MD, FACSDenver Facial Plastic Surgeon
